POP3线程安全吗?
Is POP3 thread safe?
我使用 poplib
从我的 Gmail 中检索新邮件。
我是按以下方式做的:
server = poplib.POP3_SSL('pop.gmail.com')
# ... login with credentials
#get info about new mails (1)
emails, total_bytes = server.stat()
for i in range(emails):
# get new mail (2)
response = server.retr(i+1)
我想知道如果在 (1)
和 (2)
之间 gmail 邮箱收到新邮件会怎样?
我自己尝试过,(2)
仅适用于检索有关它们的信息时的实际消息 (1)
,并且没有从服务器获取新消息。
这是否由 POP3 协议保证?
是的,POP3 锁定邮箱。
来自 RFC 1939:
Once the POP3 server has determined ... that the client should be given access to the
appropriate maildrop, the POP3 server then acquires an exclusive-
access lock on the maildrop, as necessary to prevent messages from
being modified or removed before the session enters the UPDATE state.
